Abstract

Lam., also known as Sweetie Iris, is a perennial ornamental and medicinal plant that produces a wide range of secondary metabolites. The Sweetie Iris was recently reported to have high allelopathic properties with the potential to be explored in sustainable weed management. This study aimed to identify and evaluate the contributions of compounds involved in the inhibitory effects of the rhizome of Sweetie Iris. High-performance liquid chromatography (HPLC) analysis was used to determine the content of -ionone in the rhizome of Sweetie Iris. The phytotoxicity of -ionone was evaluated on lettuce ( L.) and other test plants. The content of -ionone in the crude extract of Sweetie Iris rhizome was found to be 20.0 mg g by HPLC analysis. The phytotoxicity bioassay showed that -ionone had strong inhibitory activity on the growth of lettuce ( L.) and the other test plants, including , , , , and . At a concentration of 23.0 µg mL, -ionone inhibited the growth of all test plant species treated. Therefore, -ionone is an active compound among the other allelopathic substances contained in the rhizome of Sweetie Iris.

摘要

鸢尾兰，也被称为甜心鸢尾，是一种多年生观赏和药用植物，能产生多种次生代谢产物。最近有报道称甜心鸢尾具有高度化感特性，在可持续杂草管理方面具有潜在的探索价值。本研究旨在鉴定和评估参与甜心鸢尾根茎抑制作用的化合物的贡献。采用高效液相色谱（HPLC）分析法测定甜心鸢尾根茎中紫罗酮的含量。对紫罗酮对生菜（L.）和其他受试植物的植物毒性进行了评估。通过HPLC分析发现，甜心鸢尾根茎粗提物中紫罗酮的含量为20.0毫克/克。植物毒性生物测定表明，紫罗酮对生菜（L.）和其他受试植物（包括、、、、和）的生长具有强烈的抑制活性。在浓度为23.0微克/毫升时，紫罗酮抑制了所有受试植物物种的生长。因此，紫罗酮是甜心鸢尾根茎中所含其他化感物质中的一种活性化合物。
